Area and Circumference

Front

What is the area of a triangle?

Back

The area of a triangle is calculated using the formula: Area = 1/2 × base × height.

Front

What is the area of a circle?

Back

The area of a circle is the space inside the circle, calculated using the formula: A = π × r².

Front

What is the circumference of a circle?

Back

The circumference is the distance around a circle, calculated using the formula: C = 2 × π × r.

Front

What is the diameter of a circle?

Back

The diameter is a line segment that passes through the center of the circle, connecting two points on its boundary.

Front

What is the radius of a circle?

Back

The radius is the distance from the center of the circle to any point on its boundary.

Front

What does π (pi) represent?

Back

π (pi) is a mathematical constant approximately equal to 3.14, representing the ratio of the circumference of a circle to its diameter.

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is calculated using the formula: Area = length × width.

Front

What is the formula for the area of a square?

Back

The area of a square is calculated using the formula: Area = side × side.

Front

How do you find the circumference of a circle using the diameter?

Back

The circumference can be calculated using the formula: C = π × d, where d is the diameter.

Front

What is the relationship between diameter and radius?

Back

The diameter is twice the length of the radius: d = 2 × r.
